Type locality

Not stated by Holt & Tattersall (1905). They reported materials from four stations off Ireland, depth 199–382 fathoms (363–696 m). A rough estimate by the present author suggests that the stations are in the range of 52– 54° N, 12– 13° W.

Distribution

Previously reported from the NE-Atlantic and Mediterranean, 35– 58° N, 13° W– 14° E, depth 94–1200 m, and from the NW-Pacific off Japan, 35– 37° N, 137– 140° E, depth 220–660 m (W.M. Tattersall 1909, 1911; Colosi 1929; Băcescu 1941, 1989; Murano 1974; Nouvel & Lagardère 1976; Mauchline & Murano 1977; Mauchline 1986; Cartes & Sorbe 1995; Cartes et al. 2003; Frutos & Sorbe 2013; Sorbe & Elizalde 2013; San Vicente 2017). Frutos & Sorbe (2013) sampled this species in the near-bottom water layer. The here documented records in the SE-Atlantic at 16̄ 22° S, 3̄ 5° E, depth 5161̄ 5460 m, represent a strong extension of the known bathymetrical range; within the Atlantic also a strong southward extension (see Discussion).

Statoliths

Statoliths mineralized with fluorite, diameter 133̄169 μm (n = 6 statoliths of 3 adults).
